Two largest numbers

Question

Hi All,
I am a beginner and need help. I am writing a small program that displays the two largest numbers from a group of 10 numbers. I can have display one number but do not know how to display the second largest number.
Any help would be appreciated.
Here is the code:
----- public class MyClass1 {
public static void main( String args[]) {
int number, counter=1, largest=0, largest2=0;
String input, output;
while ( counter <= 10 )
input = JOptionPane.showInputDialog(
"Enter an Integer from 1 to 10:");
number = Integer.parseInt( input);
largest = Math.max( number, largest);
counter = counter + 1;
JOptionPane.showMessageDialog( null,
"The largest number is" + largest);
System.exit(0);
Thanks
Oamen

If you wanted to keep the format of what you're going, and not get into Collections (assumedly, you're fairly new to Java), then you could implement something like..
public class MyClass1
int first_largest = 0;
int second_largest = 0;
public static void main(String args[])
  for(int i=0; i < 10; i++)
     input = JOptionPane.showInputDialog(
     "Enter an Integer from 1 to 10:");
     number = Integer.parseInt( input);
     //i'm not going to write everything for you
     //but here, you could do some tests to determine
     //if "number" is bigger than either of your two
     //numbers, and if so, rearrange them accordingly
     //You have access to first_largest and second_largest
     //since they are both global variables.
  System.out.println("Largest: "+first_largest);
  System.out.println("Second largest: "+second_largest);
}
